AUTO MATIO WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent N o. 616,058, datedDecember 13, 1898.

Application filed July 2 l 1 8 9 8.

T0 all whom, t Wtctg/ concern.-

Be it known that I, ORION ARTHUR LITTLE, of Oxford, in the county ofSumner and State of Kansas, have invented a newand Improved AutomaticCarriage-Brake, of which the following is a full, clear, and exactdescription.

My invention relates to ari-improvement in automatic carriage-brakes orbrakes which are operated by the team, so as to be applied as soon asthe carriage runs forward upon the team.

My invention comprises the novel features hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a top plan view of the runninggear of a wagon, showing mybrake applied thereto. Fig. 2 is a longitudinal sectional elevationtaken through the center of the carriage. Fig. 3 is a side sectionalelevation of the mechanism for applying power to the brake; and Fig. 4is a bottom plan view, partially in section, showing the powermechanism.

The obj ect of my invention is to provide an automatically-operatedmechanism to be applied to carriages and wagons, such that the brakewill be applied by the mere act of the wagon running forward upon theteam. This is accomplished in the manner hereinafter described.

In the' drawings one of the rear wheels A of a wagon or carriage isprovided with a gearwheelB, secured thereto. This gear-wheel is notnecessarily secured directly to the wheel, but should rotate inconformity therewith. It might in some cases be mounted independently ofthe wheel, but should be connected with the wheel, so as to rotatetherewith. Supported upon the running-'gear is a laterally-extendingshaft C. This shaft carries a pinion B, meshing with the gear B. Uponthis shaft are mounted the two parts of a clutch, the part D beingsecured to the shaft and the part D' being loosely mounted upon theshaft. When these two parts are placed in engagement with each other, asshown in Fig. 4, they are engaged so as to rotate together. The part Dof the clutch is provided with a groove receiving one end of a link E',

Serial No. 686,501. (No model.)

lby which the clutch may be engaged while turning. The other end of thelink E is connected with one end of a bell-crank lever F, pivoted at fto the running-gear. At the opposite end of the bell-crank lever F issecured a rod G, which extends longitudinally of the reach R. To thisrod is connected a cord or cable G', which extends forward to aconnection with the doubletrees. The doubletrees I-l are mounted upon aplate I, which slides longitudinally of the tongue. By these means itwill be seen that a forward pull upon the doubletrees will Operate thelever F in such manner as to disengage the two parts of the clutch. Thetwo members of the clutch are ordinarily held in engagement by means ofa spring e, which surrounds the shaft C and bears against one end of thepart G' of the clutch. Upon the part G of the clutch is mounted a spoolE, to which is secured one end of a cable d. The other end of this cableis secured to the brake-bar K, said brake-bar being mounted upon therunning-gear in any suitable manner. This brake-bar is provided with theusual brake-blocks K', adapted to engage the wheels. A spring K2 issecured to the brake-beam in such manner as to pull it away from thewheel, and thus to release the brakes.

Upon the plate I, which supports the dou= bletree, is pivoted a lever J,having a pin O in one end thereof passing downward through a hole in theplate and adapted to engage oorresponding holes in the tongue. By thesemeans the plate and the tongue maybe locked to each other, so as toprevent sliding. The tongue will be provided with holes so located thatthe plate may be locked either in its forward or in its rearwardposition. A sulficient number of holes should be supplied to admit of asmall range of adjustment. This lever is ordinarily held upward by aspring J', so as to keep the plate and tongue disengaged. The end of thelever opposite the pin may be connected by a cord or rod J 2, whichleads to a convenient point, where it may be operated by the driver.This will enable the driver to lock the brake from the top of a load ofhay or other distant point.

It will be seen that this brake is entirely automatic in its operation,being applied by a forward motion of the wagon and released IOC by theteam pulling forward upon the doubletree. It may also be locked, so asto hold the brake on even when the team is pulling upon the doubletree,by inserting the pin O into one of the rearward holes in the tongue.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. An automatic brake-operating mechanism, comprising ashaft having a gear thereon, an intermeshing gear rotated from acarriage-wheel, a drum loosely mounted on the shaft, a spring-heldclutch mechanism adapted to connect the drum with the shaft, a cablefastened to the drum and connected with the brake, and connections fromthe draft mechanism to the clutch, whereby its parts are separated bythe operation of the draft mechanism.

2. An automatic brake-operating mechany ism for carriages, comprising adrum having a cable connection to the brake mechanism, means by whichthe drum may be positively connected to revolve with the carriage-wheel,comprising a spring acting to hold said means in operation, andconnections from the drumoperating means to the draft mechanism, wherebythe drum is disconnected when the draft is applied.

3. An automatic brake mechanism comprising a shaft having a gearthereon, an intermeshing gear rotated from a carriagewheel, a drumloosely mounted on the shaft, a spring-held clutch mechanism normallytending to connect the drum with the shaft, a cable fastened to the drumand connected with the bra-ke, a draft-bar having a sliding mounting,and connections from the draftbar to the clutch mechanism whereby theclutch mechanism will be released by the forward movement of thedraft-bar.

4. An automatic brake mechanism, comprising a shaft having a gearthereon, an intermeshing gear rotated from the carriagewheel, a drumloosely mounted on the shaft, a spring-held clutch mechanism adapted toconnect the drum with the shaft, a cable fastened to the drum andconnected with the brake, a draft-bar having a sliding mounting, alocking mechanism therefor normally held out of use, a connection, as acord, thereto, whereby it may be thrown into use at' any time, andconnections from the draft-bar to the drum-revolving mechanism, wherebyit will be released by the forward movement of the draft-bar.

5. An automatic brake-operating mechanism for carriages, comprising adrum having a cable connection with the brake mechanism, means forconnecting the drum and car riage-wheels to revolve together, actuatingmeans for said connecting mechanism normally tending to connect drum andcarriagewheels, a draft-bar having a sliding mount ing, and connectionsfrom the draft-bar to the mechanism connecting drum and wheels, wherebythe drum will be released by the forward movement of the draft-bar.
